This design first flew as Hughes Model 292 in 1956.
It was then evaluated by the U.S. Army in 1958 as a
light observation helicopter, and five production
examples were delivered to the Army as the YHO-2.
Then in 1964, the U.S. Army adopted the Model 292 as
its primary rotary wing trainer and designated it
the TH-55A Osage. A total of 792 TH-55A’s were
delivered to the Army by 1969. They were shipped to
the Army training facilities at Fort Rucker and Fort
Wolters, where often times over a hundred could be
seen in the air over the base at one time. Finally,
in 1988, the TH-55 was replaced as an Army trainer
by the Bell UH-1 Iroquois.

The museum’s aircraft’s serial number is 64-18059
and served with the U.S. Army. After its military
service, it also served with the Cleveland Police
Department. It will be restored to static condition
in U.S. Army configuration.
